Blocking directed broadcasts

["Ferino Mardo" <RMardo () ALJOMAIHBEV com>]

Our users use some services over a WAN link to our main office but not
the other way. Included in that service is Internet access for browsing.
I plan to block directed broadcasts or broadcasts in general from the
other side (main office) because some of the hosts there are
broadcasting and are reaching us.

Is this a common practice for those of you who support WAN links?

TIA.
